In earlier points I had highlighted what I consider to be an important fact: it looks almost certain that Dr Hunt hadn't seen a death from a single transected ulnar artery before conducting the post mortem on Dr Kelly. Probably not a death from any sort of incised wounds to a wrist and subsequent haemorrhage.
Norman Baker, in his book, states that Dr Hunt had only been a Home Office appointed forensic pathologist since 2001. He makes the point that Dr Hunt had little experience in that position, certainly compared with most of the other forensic pathologists on the list. In fairness though Dr Hunt stated at the Hutton Inquiry that he had been practising full time pathology since 1994.
Dr Hunt was the forensic pathologist who gave evidence at a reported inquest in 2002 as can be read here http://www.guardian.co.uk/media/2002/jun/19/broadcasting2 It can be seen that the deceased died of a very rare brain disease.
The fourth paragraph of the piece states that this was only the third instance of this rare disease that Dr Hunt had come across, 'despite carrying out thousands of autopsies'
As he had been engaged in full time pathology since 1994 I am not surprised that he had carried out thousands of autopsies. If in all that time he had never had a case of death from a cut wrist then that would be indicative of the extreme rarity of this type of fatal injury I suggest.
